Well, I bottled up an Amber on Sunday morning and planned to brew up a pale ale that afternoon. Things got busy and ran to late to brew. Then I forgot to put the yeast cake into the a jar in the fridge. Kids with learning from home really is distracting. So here it is Wednesday, yeast is still in the fermenter, cover on and with about an inch of beer over it. Can I still use it or should I dump the cake of Nottingham and start with a fresh pack?
